Jupiter: Moons Orbits JAN, 08, 2018 This visualization shows jupiter and 63 of its moons. We start close in to Jupiter showing relativly fast moving inner moons that are generally in the same orbital plane including the so called 'Galilean moons': Europa, Io, Ganymede, and Callisto. Other inner moons are: Amalthea, Thebe, Adrastea, and Metis. These inner moons orbit Jupiter as fast as about every 7 hours to about every 17 days. These moons are also relativly close to Jupiter: from around 100 tho
